ACM 231: Apple’s PrimeSense Move and Coin Is Your New Credit Card

Apple may be buying the company behind Microsoft's Kinect motion tracking, but not so you can practice your dance moves in front of your TV. Rumors say your next iPhone will be bigger, Coin is aiming to change how you use your credit cards, and speaking of credit cards, Jeff and Bryan share a couple cool products that'll make you whip out your plastic.

Earlier I had a concern about skimming of data, but now apparently the app tells you how many time your card was read. So you would eventually know if it was used somwhere else ! moreover now they are offering a morse code style pwd which you need to click after you select a card so that the waiter cannot cycle through other cards !
